COOKING STOVE.

The Schedule referred to in these Letters Patent and making part of the same.

To whom it may concern:

Be it known that I, WILLIAM G. SEMPLE, of Oincinnati, Hamilton county, Ohio, have invented cer-' tain new and useful Improvements in Cook-Stoves; and. I hereby declare the following to be a full, clear, and exact' description thereof, reference ,being had to the accompanying drawings, making part'of thisspecification.

This is an improvement in the class of stoves which are convertible from a four to a six-hole stove, or the reverse, so as to save the dealerthe expense of keepmg up a full assortment of both sizes; and

My invention consists in a new and useful arrangement of fines and extension-top, combining the advantages ,of compactness, and economy of space, material, and heat.

Figure l is a perspective view of a four-hole cook-' stove, whose top plate is made in the customary pieces A B.

Figure 2 represents the same stove, after the portion .15 has been removed, and with the addition about to take its place.

Figure 3 is a longitudinal section of the rear part of a stove, with my addition. dlFigure 4 is an enlarged view of my damper-han- A and 3 represent a customary divided top for a four-hole cook-stove. v

0 O are side plates, and D the rear plate thereof.

E E are flue-strips, which, in conjunction with the customary side and rear plates 0 C and D and the back oven-plate F, form two diving-fines, G G.

Resting on the top oven-plate H, and inclined rearwardly between the flue-strips E E, is a deflecting flue-plate, I.

The flue-strip E is perforated, and the flue-strip E and side-plateC are notched, in the manner shown, to-receive the shaft J of a damper, K, which, when elevated, asin fig. 3, acts in conjunction with the plate I, to deflect the .heat and flame upward to the two supplementary boiler-holes L L before passing down the' diving-fines G G, and which, in the depressed condition represented in fig. 2, permits the smoke to escape directly into the chimney. My addition consists essentially of two plates, 0 and P, of which the plate 0 is in skeleton form, so as to present no obstruction to the communication with the interior, and has orifices, o, to receive customary bolts, by which it is fastened 'to the body of the stove; and the plate 1? is boxed upward, as shown, so as-to afl'ord a stepped or elevated boilertop, Q, and has orifices, 1), to receive bolts or rivets, by which it is attached to the plate 0.

The plate P has shouldered flue-strips, It R, which form .an'upward-eontinuation to the strips E E,

and afford, in conjunction with the elevated top Q, a

seat or beaiing for the damper K in its closed or upper position. v

The plates 0 and I have a slight rear extension, S, for a customary collar, T, to which the stove-pipe is connected.

'Ihe shalt of the damper K hasa hinged handle.

U, having a lip, u, adapted to engage in a rack, V, upon the sideof the plate P, so as to enable'the plate I and damper K, is very effectual to deflect the heat and flames upward against any vesselsplaced upon the supplementary holes; and the supplementary flue-space M, being in direct communication with the fines G G and top flue N, without I any intervening plate, and, in fact, constituting a part or. continuation (if those flues, the heat is believed to be applied more promptly and fully to the vessels than in any other form of extension or additional stove-top.

While describing the preferred form of my invention, to vary the same in non-essentials. For example: A stove having but one or two boiler-holes, may be increased to two or four holes in the. above manner.

The advantages claimed for this arrangement, over its nearest analogues, are- First, great compactness; taking up scarcely any more room from front to rear than a common fourhole. j 7

Second, economy of heat. The portiohs M of the flue being merely a direct continuation upward of the ordinary flue, instead of a chamber, separated by the top plate of the stove-body or thebottom plate of the extension, (as in the Vedder, Thornilly, and others of that class,) the vessels being right over the open flue of the stove proper, and receiving the heat therefrom, deflectedupwardby the reverselycurved plates I and K, the action of cooking-is expedited.

Third, economy of material, avoiding an intervening plate, and any considerable extension rearward.

I claim herein as new, and of my invention- 1. The convertible four and six-hole cook-stove,

substantially as set forth.

. 2. The elevated and open-bottomed addition 0 P,v

, 5. In combinationwith the strips n E and n R, or their equivalents, the deflector I and damper K,

formed and arranged as forth.

In testimony of which invention, I hereunto set my and for the purposes set Witnesses: Gno. H. KNIGHT, JAMES H. LAYMAN.
